  • Publication number: 20240348478
    Abstract: This disclosure relates to a communication method and apparatus. A terminal device obtains M channel estimation results corresponding to M time units, where M is greater than 1. The terminal device performs joint compression on the M channel estimation results by using an encoder network, to obtain N pieces of compression information. The terminal device sends the N pieces of compression information to an access network device. Because the terminal device performs joint compression, correlation between downlink channels at different time points is fully utilized. The access network device recovers the N pieces of compression information obtained through joint compression, so that more accurate and effective downlink channel information can be obtained.

  • Publication number: 20240137082
    Abstract: A communication method and apparatus. A terminal device determines channel state information based on S indexes of S vectors. Each of the S vectors is included in a first vector quantization dictionary. The first vector quantization dictionary includes N1 vectors, where N1 and S are both positive integers. The terminal device sends the channel state information to a network device. Because a vector included in the vector quantization dictionary usually has a relatively large dimension, quantizing channel information by using the first vector quantization dictionary is equivalent to performing dimension expansion on the channel information or maintaining a relatively high dimension. High-precision feedback is implemented by using relatively low signaling overheads.
